BYTE-WRITING MACHINE.

Application filed March 5, 1910. Serial No. 547,416.

To all whom it may concern:

Be it known that L'FRANK A. YOUNG, a citizen of the United States, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specifloat-ion.

This invention relates to the tabulators commonly used in conjunction with the earriages of typewriting machines, the object of the invention being to provide improved means for locking the stops to the bar on which they are mounted and along which they are adjustable.

The improvement is illustrated in connection with the tabulator shown in my Patent 961,280, dated June 14:, 1910.

According to the present invention, the column stops consist of forks which bestride a column stop rack, the forks being adjust ably seated between teeth formed on oppo- I extend the forks down below or beyond the rack, and contrive, by means of these extended portions, to lock the stops against upward displacement or wit drawal from the rock. This locking is effected by a locking bar which, extends along the rack ha r between the forks but when rotated to another position it turns into notches provided in said extensions of the forks, and t; reby prevents them from lifting. Other objects and advantages will hereinafter appear.

View of the same. 3 and 4 are crosssectional views illustrative of the operation of part The re erence numeral 3 marks a bar which is rigidly connected to the -frame of the ty 'iewriting machine (not shown) by the brackets 3', the be r non. the brackets being secured to each other, as by screws 4-. This bar 2 is adapted to hold the tnbulator'stops 5 by ireans of the melt teeth. at the front and rear sides of sad bar and the parallel legs C, 7 forming part of said step, which- Specifioation of Letters Patent.

tion in one direction transverse to said bar.

' A rocking bar is adapted to move into and out of position'for looking such stops against such transverse motion. Such rockin box may co-act with the stops in any su table manner, as with a corner or shoulder thereon, or with a notch on an edge of the" stop which is substantially parallel with the direction of motion of the stop in putting it on the bar 25 In the arrangement shown in the drawing, a rocking bar is shown at 8; it is journaled in lugs or cars 9 on the under side of the fixed bar 2. This bar 8 is of a transverse dimension (1 in one direction greater than its transverse dimension 3) in another direction, and such greater dimen sion is greater than the width of the slot 10 between the legs 6, 7 of the stops at the open end of such slot. The slot 10 is widened at a point between its open and closed ends to alow the rod 8 to no turned so as to bring the wider part a across -or transverse to the length of slot 10 and thereby prevent the removal of the stop from the bar 9, as indicated in Fig. 3. By turning the rod 8jto the position thereof shown in Fig. fl, the stop is released for removal from the bar 2, as the dimension 5 is less than the width of the slot 10. In the instance illustrated, the

widened part of the slot 10 consists in a notch 11 in one of the edges of the metal leg 7 thus forming a'sort of shoulder at one side of slot 10. By using a round rod. 8

which is flattened on one side, as at 12, a simple, durable and convenient lock is provided for retaining the stops in place on the bar 2.

A. knob 13 is fast on the rod 8 at one end one direction While motion of said rod 8 in the reverse direction is prevented by a pin 15 in said rod, and by a lug 9.

It Wlll be observed that one rod or bar 8 r" -acts with all-the stops 5 whatever may be their position along the bar 2, and that it loclrs ens. unloolis ell of them simolteoo seirl oer between teeth thereof, slot ofseicl stop being widened ea: or point between the open and she closed ends thereof, eml a journeleol siege-lock of? 9.
